Created attachment 37008 [details] [review] Seems this patch works for me We met this issue when trying to run OpenGL ES conformance test suite This is a bug introduced by me when switching to use a dynamic array to manage EGLConfigs and EGLScreens. I've committed an alternative fix (d7284b) to fix both eglGetConfigs and eglGetScreens.
